Modine 5H0730570003 — 200°F Manual Reset Blocked Vent Switch
The Modine 5H0730570003 is an OEM manual-reset blocked vent switch designed for use in Modine unit heaters. Rated at 200°F, this safety device monitors flue and vent conditions, automatically shutting down the heater if a blocked or restricted vent condition is detected. Once the unsafe condition has been resolved, the switch must be manually reset before the heater can resume normal operation — providing an added layer of protection against repeated unsafe cycling.
Key Features
- 200°F temperature rating for reliable high-temperature detection
- Manual reset (M/R) operation — requires deliberate technician reset after trip
- Blocked vent switch function protects against flue and exhaust restrictions
- OEM Modine replacement part for compatible unit heater models
- Helps prevent carbon monoxide buildup and heat exchanger damage caused by venting failures
Application
This blocked vent switch is a critical safety component in Modine gas-fired unit heaters. It is typically mounted in the vent or flue path and responds to abnormal temperature rise caused by restricted exhaust flow. The manual reset design ensures that a qualified technician inspects and clears the cause of the blockage before restoring heater operation, making it an essential safeguard in commercial and industrial heating applications.
